| 238 | Ultrasonic conditioning and wet scrubbing of fly ash | US135683 | 1998-08-18 | US5988396A | 1999-11-23 | Rafic Y. Minkara; Jerry L. Heavilon |
| Processes for treating fly ash to enhance the fly ash as a pozzolan for portland cement mixes and to separate therefrom a substantial carbon compound and/or to increase the fineness of the fly ash include the treatment of a fly ash slurry with ultrasonic energy using ultrasonic horns immersed in a slurry of fly ash and water and imparting to said slurry such ultrasonic energy as to cause microscopic cavities to form and implode with high localized energy to break up fly ash agglomerations along cleavage lines and to break up carbon particles and matrices which have entrapped fly ash microspheres therein to release the microspheres into the slurry. A conditioner agent may be added at or during ultrasonic treatment to enhance the flotation of the carbon compound. | ||||||
| 239 | Method for processing gold-bearing sulfide ores involving preparation of a sulfide concentrate | US423839 | 1995-04-18 | US5653945A | 1997-08-05 | John C. Gathje; Gary L. Simmons |
| Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in sulfide minerals, is obtained by flotation. In one embodiment, nitrogen gas is used to substantially prevent contact between the ore and air during comminution of the ore and during flotation operations. It is believed that oxygen gas present in air detrimentally affects the recovery of sulfide minerals in a flotation concentrate through surface oxidation of sulfide mineral particles. The use of a gas such as nitrogen can significantly reduce the potential for such surface oxidation. Additionally, gases separated from an oxygen plant may be beneficially used, with an oxygen gas stream being used, for example, for pressure oxidation of sulfide mineral materials, and with a nitrogen gas stream being used in comminution and/or flotation operations, resulting in advantageous use of a nitrogen gas by-product stream which has previously been vented to the atmosphere as waste. | ||||||
| 240 | Method of removing dissolved oil from produced water | US665741 | 1984-10-29 | US4627922A | 1986-12-09 | Carrol L. Viator; Glenn E. Gilley; Paul C. Broussard, Sr.; Curtis Broussard; Dennis Gracy |
| This invention involves a process and apparatus for removing dissolved and undissolved oil and chemical additives from waste and/or produced water streams. The process involves contacting a selected gas with the produced water stream, the selected gas utilizing hydrogen bonding and dipole interactions with the contaminants to remove them from the water. The rise rate of the selected gas is accelerated by mixing natural gas with the selected attractive gas. The selected gas and natural gas are recovered by the application of vacuum to the waste stream after treatment. The selected gas is separated from the natural gas by compressing and cooling the combined gas stream, venting the majority of the natural gas stream while the selected gas is liquified, then expanding the selected gas before returning it to the flotation vessel. Means are also provided for mixing the selected and natural gases with the contaminated water stream at line pressure so that mixing is intimate and flotation is accelerated. | ||||||
